[Speex-dev] visual studio 2005 - help getting speex workin'

[monk at rq3.com]

I got this working.  For anyone curious, here's what I ended up doing:

Looking at the speex 1.2rc1 VS2005 .sln, I found that I shouldn't bother
using FLOATING_POINT, FIXED_POINT, or USE_ALLOCA.  Instead, I should use
HAVE_CONFIG_H.  When I did that, the compiler complained that it could not
find config.h.

I copied config.h from the "win32" folder in speex-1.2rc1.tar.gz into
ioquake3's \libspeex folder, then dragged that file to the "speex" Visual
Studio filter that I had defined before.

After that, I had a bunch of warnings, but no errors.  And the compile
succeeded.  Yay!  I see whoever did the Visual Studio files also put in an
ignore of warnings 4244, 4305, 4311, 4100, 4127, and those are pretty much
the speex-related ones I get:

..\..\code\libspeex\vbr.c(83) : warning C4305: '=' : truncation from
'double' to 'float'
..\..\code\libspeex\vbr.c(88) : warning C4244: '=' : conversion from
'double' to 'float', possible loss of data
..\..\code\libspeex\stereo.c(274) : warning C4100: 'state' : unreferenced
formal parameter

...etc.

So I assume those are minor and already known.  I checked the resulting
binary and the VOIP-related variables were active in-game, so that's good
enough fer me.  I have gotten this working on Win2K with Visual Studio
2005 and will also test it with WinXP and Visual Studio 2008, though I
don't anticipate any real differences between the two platforms, now that
I got the basic compile going.

Thanks again for those who offered suggestions and thanks especially to
those who maintain the Visual Studio/win32 files!
